There are now 15 Amazon Go stores, located in Seattle, Chicago, San Francisco and New York.

Amazon has added two Amazon Go stores, in New York City and San Francisco, bringing the total number of locations to 15.

The New York store is located in Midtown Manhattan and spans 1,450 square feet. This is the third New York City Go store. The San Francisco store measures 2,125 square feet and is the fourth Amazon Go store in the city.

Both stores offer staples, meals and snacks, including Amazon Meal Kits. Amazon stock, which recently suffered its longest losing streak in 13 years, is still up 17.5% for the year to date, according to Market Watch.

Amazon has plans to open three additional Amazon Go stores, one in Seattle and two in Chicago, according to Retail Dive.

A timeline for these stores has not been disclosed. But the company said that the new store in Seattle will be approximately 1,150 square feet. In Chicago, the stores will be located at the Prudential Plaza and the Merchandise Mart — 1,425 square feet and 930 square feet, respectively.

According to Retail Dive, the latest store openings appear to be part of Amazon’s plan to expand further into the brick-and-mortar retail market.

A report by RBC Capital Markets estimates that if the online retailer opens as many as 3,000 locations over the next few years, the company could bring in $4.5 billion in revenue by 2021, a figure based on estimated revenue of $1.1 million and $1.95 million in revenue annually per Amazon Go store.
